1、Designation:F230010Standard Test Method forMeasuring the Performance of Personal Cooling SystemsUsing Physiological Testing1This standard is issued under the fixed designation F2300;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、 year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONIndividuals in various occupations are exposed to high heat stress resulting from increasedmetabolism,or the envi
3、ronment,or both.Environmental heat stress can be especially severe whenindividuals are required to wear Personal Protective Equipment(PPE),which impairs or preventsevaporation of sweat from the skin,and thus nullifies the bodys principal means of removingmetabolic heat.Failure to dissipate this heat
4、 can dramatically limit work capacity and heat tolerance,thereby increasing the risk of heat-related illness.To reduce this risk,workers are wearing PersonalCooling Systems(PCS)to extend their exposure time to thermal stress.These systems are intendedto limit the effects of external environmental he
5、at and the internally generated metabolic heat on thebody.For this purpose,standards that objectively quantify the effectiveness of PCS are essential.Therefore,tests that measure important physiological variables,such as core temperature,are essentialin evaluating PCS applications and increasing wor

7、fects of thermalstress.1.1.1 To increase safety during physiological testing,thisdynamic test requires the use of human participants whoexhibit specific health and physical fitness requirements.1.2 This test incorporates the use of protective clothingensembles(outer garments)used in conjunction with
8、 or wornover top of the PCS.This scope is therefore oriented toindustrial rather than athletic applications.1.2.1 The effectiveness of different PCS will be quantifiedwith the same protective clothing ensemble.Therefore,thephysiological values obtained apply only to the coolingsystems,the particular
9、 protective outer garment,and thespecific test conditions.1.2.2 When a protective outer garment is not provided,thistest method requires that PCS shall be tested with the standardouter garment defined within this test method.1.2.3 The present standard does not attempt to determineimportant clothing
10、characteristics,such as thermal insulationand evaporative resistance,of the PCS or of the garments wornwith the PCS.Test Methods F1291 and F2370 can be refer-enced for these clothing measurements.1.3 The values stated in this test method shall be SI units.1.4 It is the responsibility of the test lab
